Mount Aso Geology

Posted in Nature, Places by tokyobling on September 17, 2015

Once I started looking at my old photos of Mount Aso in Kyushu’s Kumamoto Prefecture I found lots of interesting ones. These photos are from the other craters at the volcano. There are actually four clearly visible craters, but since 1934 all but one has been inactive. I have no doubt they will wake up again some day. Here you can clearly see examples of agglutinates, which is a lava-like form of scoria that rapidly deposits around the crater edge at an eruption. I can imagine this place must be heaven for volcanologists and geologists! For me, telling agglugates from lava and scoria from magma is a tough task though. Sadly geology was not covered very much in my school days. Still, I imagine that Mars would look something like this, minus the skies, clouds, water and vegetation!

    Amazing photos! Mt. Aso has recently erupted (on Monday), although it’s not clear if it was a magmatic eruption or a steam eruption. It’s been on alert since activity started April or May.
